A STUDY OF OPTIMUM DESIGN OF AXISYMMETRICALLY LOADED CONICALL SHELL

축대칭 하중을 받는 원추Shell의 최적설계에 관한 연구

This paper presents the optimum design of reinforced concrete conical shell which is fixed at the base and free at the top. The calculation of stresses is done using the SMAP(Segmented Matrix Analysis Package)program which uses the simple finite element method of analysis. The objective function contains the ratios of the unit cost of reinforcements and formwork to that of concrete. To Simplify the optimization procedure, the final optimum design of conical shell is obtained by combining the result of each element. The results are presented and discussed.
